Overview
R7FS5D37A3A01CFM#HA0 from Renesas Electronics is a 32-bit ARM Cortex-M4F-based microcontroller in the Synergy S5 Series, featuring 2 MB flash, 512 KB SRAM, integrated FPU, AES-256/SHA-256 crypto engine, and dual CAN FD interfaces. It operates at up to 180 MHz, supports industrial temperature range (−40°C to +105°C), and targets secure industrial HMI and gateway applications requiring real-time control and encrypted communication.
For engineers reviewing the R7FS5D37A3A01CFM#HA0 datasheet, R7FS5D37A3A01CFM#HA0 pinout, R7FS5D37A3A01CFM#HA0 application, or R7FS5D37A3A01CFM#HA0 equivalent, key selection criteria include its dual CAN FD support with time-triggered capability, hardware crypto acceleration, 180 MHz deterministic execution, and IEC 61508 SIL2-ready safety features for functional safety–critical edge nodes.
Technical Context
The R7FS5D37A3A01CFM#HA0 implements an ARM Cortex-M4F core with FPU and MPU, coupled with a multi-layer AHB/APB bus matrix enabling concurrent peripheral access. It integrates a configurable interrupt controller (ICU) with 240 priority levels and supports vector table relocation for bootloader flexibility.
Its clock system includes on-chip FLL and PLL, supporting multiple clock sources (HOCO, LOCO, MOSC, sub-clock, and external crystal), with independent domain clocks for CPU, peripherals, and USB. The device provides three independent power domains (VCC, VCCIO, AVCC) and supports low-power modes down to 0.25 µA in deep software standby with RTC wake-up.
